# I have found a solution on the dynamic ip address problem I mentioned in my responses.

I am using the AWS IP range JSON file here, <a class="a a--md" elv="true" href="https://ip-ranges.amazonaws.com/ip-ranges.json">https://ip-ranges.amazonaws.com/ip-ranges.json</a>, to associate the EC2 eu-west-1 region with a range of IP addresses.

The Rublon MFA API now uses static IP addresses, which should allow you to resolve this issue: https://rublon.com/blog/rublon-api-now-uses-static-ip-addresses/

When I was looking for a good proxy service, I looked into a lot of different providers to find the one that would work best for me. But in the end, I chose https://infatica.io/residential-proxies/ because it was reliable and had great customer service. Now, working on the Internet is much safer and easier than it used to be.
